Antrodia cinnamomea is a highly valued folk medicine used for liver cancer, a disease often caused by the long term infection of hepatitis C virus (HCV). In the present study, the maleic and succinic acid constituents (antrodins A–E) of this medicinal fungus, the in vivo metabolites of antrodin C and the analogue of one of the metabolites were tested for their inhibitory activity on HCV protease. Most of the compounds showed potent inhibitory activity, with antrodin A being the most potent (IC50 = 0.9 µg/mL). Antrodin A was isolated as one of the constituents of A. cinnamomea and was also detected as an in vivo metabolite of the major constituent antrodin C. The mode of inhibition for antrodin A on HCV protease was revealed by a Lineweaver-Burk plot as competitive inhibition. These results strongly support the use of this folk medicine for liver cancer and HCV infection which is a global problem. Copyright © 2008 John Wiley & Sons, Ltd.
